What could this be?

Latley I've been feeling so sad over nothing, feel like I dont want to be around anyone, I just want to be alone. I feel hopeless. I get go angry over the littlest things. Its mostly because of my best friend, she always rubs things in my face when she...

gets something new , now I dont think of her as my ''best'' friend. please anyone help, I cant stand this .

I think you're a little depressed, dear.

Anger, mood swings, emotional rampages, and easy irritation are a few signs.

yeah your just depressed .take it easy .
Some people keep there mind open so nothing is inside . Let it out . Right a poem on how you feel . Kick back with a couple of friends . Cccchhhiiilll . That's all.
avoid the people that is affecting you

yeah, its depression, but dont think bad yet, I had sumthing like that for a while, because I worried my self a lot, and stress, just go and chill with friends, go have fun, just chill out, and try to stay away from people, or stuff that mite make you mad, or sad. key word is CHILL.
